In simple terms: - Making one exposure and than adjusting it once out of the camera always locks you into whatever happens to be the maximum analog dynamic range of the sensor. If elements of a scene fall outside that dynamic range, you get black/noise or total saturation, no matter how much adjustability a RAW converter might have or how much data recovery it can do.
- Making a set of exposures at different exposure settings and then integrating them together allows you to window the scene with a dynamic range wider than what the sensor can acquire in one exposure.
